A newmethod is discribed for introducing a CF3-group, by a single-step synthesis, into aromatic compounds. This trifluoromethylation is done by means of a mixture consisting of HF/CCL4 and the aromatic compound. The reaction is thought to be of a Friedel-Crafts type and limited to aromatics which are not substituted by electron withdrawing groups.

C–O/C–S crosscoupling of arylhalides with phenol or thiophenol was studied under ligand-free condition at room temperature over CuO nanocatalyst. The scope of the reaction was extended to various arylhalides and substituted phenols under optimized condition. In general, efficient, selective, and reusable heterogeneous nano CuO catalytic system has been developed for room temperature C–O and C–S

Both N- and T-type calcium ion channels have been implicated in pain transmission and the N-type channel is a well-validated target for the treatment of neuropathic pain. An SAR investigation of a series of substituted aminobenzothiazoles identified a subset of five compounds with comparable activity to the positive control Z160 in a FLIPR-based intracellular calcium response assay measuring potency
N型和T型钙离子通道均与疼痛传递有关,并且N型通道是治疗神经性疼痛的有效靶点。对一系列取代的氨基苯并噻唑的SAR研究在基于FLIPR的细胞内钙反应测定法中测定了在Ca V 2.2和Ca V 3.2通道的效价,确定了与阳性对照Z160具有可比活性的五种化合物的子集。这些化合物可能构成开发药物前导和工具化合物的基础,这些化合物和工具化合物用于评估Ca V 2.2和Ca V 3.2通道的可变调节的体内作用。
